i love my livescribe pen, i use it so often in my work, these days i would not know how to operate without it. i find it brilliant with all the different ways of interfacing with handwriting and computers.
however, i find the ink on the pen refill to last only a few pages, which i find, for the price is a bit disappointing. i tend to use the medium black instead of the fine, because the fine tends to make more friction noise in the recording, which think may be related with the way that i make pressure on the page. this was largely resolved by the medium point. finally, sometimes, it appears as if the ink dries out as well, if you dont use the pen regularly enough. it may be a good idea to develop longer lasting ink refills. overall, i find the pen such a good tool that this issue has not put me off from using it
